Compatibility «Amlodipine» and «Dexamethasone»

• Interactions Amlodipine with Dexamethasone

  • Dangerous interactions
    • ⓘ Regardless of the status of the CYP3A5 genotype, the possibility of interaction with these drugs cannot be excluded.
    • ⓘ Calcium channel blockers(C08) + Drugs that cause hypokalemia; Glucocorticosteroids (C03A, A01AB04,J02AA01,H02,D07 => Increases the likelihood of ventricular tachycardia and ventricular fibrillation. (A dangerous combination, it is necessary to eliminate hypokalemia before use).
  • Negative interactions
    • ⓘ However, a 3-fold increase in plasma exposure to tacrolimus was reported in a kidney transplant patient (non-CYP3A5 expressor) after starting amlodipine for the treatment of post-transplant hypertension, which led to a decrease in the dose of tacrolimus.
    • ⓘ Reduction of the antihypertensive effect of amlodipine (due to fluid retention and sodium ions as a result of the action of corticosteroids).
    • ⓘ Inhibitors of the CYP3A4 isoenzyme.
    • ⓘ Caution should be exercised when using dexamethasone (CYP3A4 inducer) with amlodipine at the same time due to a possible increase in hepatic metabolism of amlodipine (CYP3A4 substrate).
    • ⓘ Caution should be exercised and the therapeutic response monitored when using CYP3A4 inducers, such as dexamethasone, with amlodipine (CYP3A4 substrate), etc.; an increase in hepatic metabolism of amlodipine is possible.
  • No interactions
    • ⓘ Since amlodipine is a weak inhibitor of CYP3A4, the exposure of mTOR inhibitors may increase when used together.
  • Positive interactions
    • ⓘ A prospective study involving healthy volunteers from China (n=9), CYP3A5 expressers, showed an increase in tacrolimus exposure by 2.5-4 times when used concomitantly with amlodipine compared with the use of tacrolimus alone.
    • ⓘ An increase in the dose of amlodipine may be required.
  • Unclear interactions
    • ⓘ This result was not observed in individuals who did not express CYP3A5 (n=6).
    • ⓘ Corticosteroids (mineral.
    • ⓘ And glucocorticosteroids), tetracosactide.
    • ⓘ Amiodarone, amlodipine + amiodarone.

Decoding the colors of interactions and contraindications

Dangerous	—	a pronounced negative interaction or contraindication.
Negative	—	negative interaction or side effect that may reduce effectiveness.
Positive	—	the interaction can SOMETIMES be used as a positive (often a dose adjustment is needed), or it is an indication of the drug.
No	—	the drugs do NOT interact, which is separately indicated in the instructions.
Unclear	—	the system failed to pre-assess the danger.
